It's a normal afternoon, except it's a little humid and cool after a heavy rain. You enter the campus, climb the stairs, and arrive back at your classroom. Your eyes glance at your usual seat at the back, but there's something there. As you get closer, you see a glass of ice water and a sticky note.

You immediately ask your nearby classmates, but they also say it was already there before they arrived. The sticky note only has encouraging words and cute emojis written on it. You have no idea who left it there.

You don't know that it was Rio who left it there, the campus heartthrob sitting in front. She's quietly smiling there, stealing glances at how you're looking around in confusion.
